French observability startup Tsuga lands €30 million to expand AI agent platform

Founded in 2024, the platform deploys inside the customer’s own cloud across any environment so telemetry never leaves their control, infrastructure costs are reportedly eliminated at source, and AI runs on complete, unsampled data.

Six months after exiting stealth, Tsuga has grown to several millions in revenue with average contract values in six figures, and customers including frontier model labs like Black Forest and enterprise customers like Le Monde, Camunda, and Buk.

According to the company, the observability industry has run the same playbook for decades: ingest customer telemetry, store it in a third party cloud, and charge exponentially more as volumes grow.

The AI era has made that approach untenable: every agent loop, every autonomous deployment, every token interaction generates observability data at volumes legacy platforms were never built to handle. Ingestion costs compound. Sampling increases as customers manage their spiraling spend. Governance gaps open as sensitive AI interaction data flows to third-party clouds.

Tsuga says platforms that dominated the last era are not struggling because of a feature gap. They are struggling because their entire architecture was built on an assumption the AI era has made obsolete.

The platform deploys inside the customer’s own cloud account, across Microsoft Azure, AWS, Google Cloud, and regional sovereign clouds, so telemetry never leaves their environment. There is no infrastructure tax, no duplication cost, and no sampling.

Pricing is a single rate per GB of consumption, and costs allegedly fall as Tsuga’s engineers tune the environment over time.

“Tsuga has the architectural scalability, flexibility and distributed platform support that the coming generation of AI-native applications and agents require in their observability platform. This is a step-function change only possible because of their innovation across the full stack, from the storage layer to the business model,” says Alexandre Momeni, Partner of General Catalyst.
